Distribution cables

Distribution cables cover a range of voltages from 132 kV to 11 kV. These cables can have various designs which leads to different levels of magnetic fields. On this page typical levels of magnetic field from 132 kV and 11 kV cables are given but the exact fields from any specific cable will depend on the design and the way that it operates.

The maximum fields from the largest 132 kV cable are given below. This demonstrates that even for the maximum possible field for a distribution cable, the public exposure guideline level is not exceeded and therefore these cables are always compliant.
